This is the only flavor that my boyfriend will drink. He loves it. Tastes pretty similar to the zero ultra monster. It's not my favorite flavor because it kind of just has that energy drink taste if you know what I mean. I do wish that they had more sugar free flavor options.

I'm a lifer when it comes to this version of redbull. I've been drinking this for over a decade. It taste great, doesn't have a weird aftertaste like some of the other sugar free energy drinks. It's the perfect size and still packs a plus without the crash!

Looking for something not too sweet we'll here it is. Sugar free Red Bull. Very good and will give you a caffeine rush to wake up if your feeling tired, or lazy. Not only that but it has only 20 calories which awesome because we all know a lot of people try to stay away from calories.

What makes sugar free Red Bull so much better than the other varieties? No idea at all but it's definitely true because every time I go to my local convenience store, the sugar free version is sold out. It's a nice, light flavor and gives you energy in a very approachable way.

A little more expensive than Monster but there is usually a good deal when you buy more than one, I am definitely a repeat customer. My only beef is the price, because a small can is more expensive than the alternatives but it is my favorite and would definitely recommend Red Bull Energy Drink, Sugar Free

I absolutely love the sugar-free option from Red Bull. Each 8.4 fl oz can is a fusion of caffeine, taurine, and B-vitamins, yet only contains 10 calories. So you can power through your day without worrying about crashing later on. Buying in bulk is more cost effective than purchasing one individually when drinking 1 a day. All in all it's a great start to the day.

Absolutely love this for the perfect afternoon and morning boost. As a working mom i am always looking for easy ways to incorporate energy boosting products into my day - after all toddlers are not easy! The taste is so good and i do not have an afternoon crash with redbull. Definitely recommend.

My favorite redbull by far! Whenever I need a little pick me up I will swing by the gas station and pick one of these bad boys up. Gives the perfect kick and always readily available. Love that it has zero sugar! To me it's the best tasting redbull I've tried

My partner drinks these daily. To be honest, I can't stand the flavor unless it's mixed with something else. My partner hates the flavor too, lol, but he keeps drinking them because there's no added sugar, and these days so many energy drinks have SO MUCH caffeine. The 8.4 oz can has 80 mg, comparable to a small cup of coffee, which is just about right. When lots of energy drinks on the market have ~200 mg caffeine, it makes sense that this god-awful tasting red bull keeps making its way into our fridge.

Sugar-free Red Bull is a decent alternative for those looking to cut down on their sugar intake, but in my opinion, the regular version tastes better. The flavor of the sugar-free version is slightly artificial and not as satisfying as the original. Additionally, the energy boost from the regular version seems to be more pronounced. That being said, the sugar-free version is still a good choice for those who are trying to reduce their sugar intake and are looking for an energy boost. It's just not quite as good as the real thing.
